video_core: NVIDIA DLSS through NVIDIA Streamline in place of a game's DLSS

2026-11-03T17:33:16+00:00

Adds a Graphics setting, "Use NVIDIA DLSS in place of a game's DLSS" (nvidia_dlss, off by default). When it is on, in Windows builds configured with EGLANTINE_STREAMLINE_SDK, the evaluation Eglantine already replaces with FSR 3.1 goes to NVIDIA DLSS on GeForce RTX cards, with the same inputs (colour, depth, motion vectors, jitter). When DLSS can't run, FSR 3.1 runs as before. Only Streamline's MIT-licensed headers are compiled in; nothing of NVIDIA's is linked or shipped. At run time Eglantine looks for sl.interposer.dll in the user folder's "streamline" folder (or EDEN_STREAMLINE_DIR, or "streamline" next to the executable), checks its Streamline signature and starts Streamline with manual hooking. Streamline's plugins come from that folder or the NVIDIA app's downloads. DLSS itself is nvngx_dlss.dll in the same folder, else the newest DLSS 310 or later that the NVIDIA app has downloaded, checked for NVIDIA's Authenticode signature and copied as streamline/nvidia-app/nvngx_dlss.dll. Like other tools that call DLSS outside a game, it uses its own fixed project id with the custom engine type. - Preset K for all modes (EDEN_NX2_DLSS_PRESET overrides it): the default Performance model (M) and L draw thin dark horizontal lines in some frames at 2x resolution scale; K doesn't. - HDR input with auto exposure; the mode follows the render/output ratio. - Buffer device address stays enabled when DLSS needs it, for DLSS only. - The upscaler waits for the device instead of submitting when it is destroyed: by then the game's channels are released, and a submit read the state tracker's stale flags (a crash when stopping a game). With the setting off, or in builds without the SDK path (the setting is hidden there), nothing changes. Testing: Windows 11, RTX 5080, Fire Emblem: Fortune's Weave docked at 1x (720p -> 1440p) and 2x (1440p -> 2880p), CLI runs and GUI play, stopping and restarting games with DLSS on. Not tested on other GPUs or games. Assisted-by: Claude Opus 5.5 (implementation, debugging) Signed-off-by: Duck912 <350528965+Duck912@users.noreply.github.com>

common: measure the TSC only on CPUs without CPUID leaf 0x15 (#373)

2026-11-03T06:28:21+00:00

The fallback that measures the TSC rate when the CPU reports none was meant for AMD, which has no leaf 0x15 at all. It also caught Intel CPUs that have the leaf but report a crystal frequency of 0 (Coffee Lake, e.g. the i5-9400F) and moved them from the OS clock to the measured RDTSC clock. With the same fallback in another Eden-based build, an i5-9400F crashed about 3.5 s after launch; limiting the fallback to CPUs without the leaf fixed it for that tester. Those Intel CPUs now keep the OS clock, as before the fallback. AMD CPUs still get the measured RDTSC clock (a Ryzen 7 9800X3D reports max leaf 0xd, so nothing changes there).

network: close each bsd fd once and drop unwanted or malformed room packets

2026-11-03T00:39:54+00:00

Two threads closing the same fd both copied the descriptor and both called Close(), so a host socket could be closed twice, and the second closesocket could hit an unrelated socket that had reused the host fd. CloseImpl now frees the slot under file_descriptors_mutex first and only that thread closes the socket; the other gets EBADF. OnProxyPacketReceived decompressed every room packet when any fd had a socket, including native sockets and proxy sockets on other ports. Sockets now report through AcceptsProxyPacket whether they want a packet, and only those are collected, so an unwanted packet is not decompressed. DecompressDataZSTD passed the frame's declared size straight to the vector constructor, so a malformed or unsized frame from a room member threw on the room thread. The new TryDecompressDataZSTD rejects invalid, unsized and oversized frames, and bsd drops such packets with a warning. DecompressDataZSTD now returns an empty vector for them instead of throwing.

core: skip empty bitmap ranges during cache and scheduler traversal

2026-11-02T19:07:54+00:00

Adapted bitmap scans from sylvieistaken/selevet-eglantine performance build 4. Keep the wide-priority fallback and fix the first live slot after empty bitmap words. Include randomized lifecycle and ordering checks. Assisted by Codex.

Merge nx2 into nx2-experimental

2026-11-02T13:43:01+00:00

Resolved by area: - audio feature_support.h: nx2's native revision handling. - fiber.cpp: ours, which also drops the unused rewind stack. - host_memory.cpp: ours granule bitmap and HintCold, plus nx2's fallocate hole punching per whole dirty granule on Linux. - texture_cache.h: nx2's old-age eviction pass, then our Collect(). - kepler_compute.cpp: shared upscale slots, then Fortune's Weave's, then the Kirby Air Riders scan. - nx2_gsv.h: ours, plus nx2's GetBufferMaxResolution and graphics device ids (1-based). - nvhost_ctrl_gpu.cpp: engine support flag bits 40-44. - lower_to_maxwell.h: ours as the base, with nx2's seven lowering commits applied one at a time. Second texture descriptor buffers are read bindless in TEX, TLD.SCR (level zero) and SUST; FSEL keeps its operand modifiers; TXD takes any channel mask. lower_to_maxwell.h lowers 837 Fortune's Weave and 1183 Mario Kart World shader dumps with the same rejects as nx2 and ours (12 and 0).
